New A/C and Furnace
I have had a couple quotes on new A/C and Furnace in a home with original equipment dating back to 1989. I am leaning towards either York or Carrier. In trying to do my due diligence with research, you here good and bad for both companies. I am looking for opinions on the following systems:
1. YORK AFFINITY FURNACE YP9C 98% Eff. 80,000 BTU WITH A LATITUDE TCGF 15+ SEER A/C UNIT
2. CARRIER INFINITY FURNACE 58MVC 95%Eff 80,000 BTU WITH A PERF SERIES 16.5 SEER A/C UNIT
The quotes are from several reliable contractors in my area, I realize the installation is as important as the actual equipment and lowest price is not my main consideration.
I would really appreciate any opinions on positives and negatives on the 2 systems? Also if the professionals on this forum think that these 2 manufacturers are not the best option please let me know.
Thanks in advance !!
Have you had an energy audit done on your house yet? Did these contractors perform manual J calcs on your home?
An answer without a question is meaningless.
Information without understanding is useless.
You can lead a horse to water............
** THIS IS NOT FOR ADVICE, BUT PURELY MY SUMMARY. I AM JUST A HO and NOT A PRO. **
Thanks to this forum, I have realized the following:
a) No matter what existing system one has already along with the ductwork present, if that's old enough there should be an attempt by HO to have the manual * calculations done prior to purchase of such a significant item.
b) It's better to do the walk / refer to the location map as in this forum to take the advice of HVAC specialists rather than depending on big box store contractors.
c) The standard HO buying process of a new gas/electric furnace + AC is okay but today there are multiple options whereby it's significantly more efficient to consider alternatives/add-ons like heat pumps, geo-thermal, etc. As such, a good HVAC specialist can advice hollistically considering all these options.
d) Additional add-on items like EAC cleaners, humidifiers, etc. along with cutting-edge thermostats are offered but should be carefully evaluated on need basis once again requiring good HVAC specialist.
e) Effectively, a true HVAC specialist normally comes to the same and in fact in most cases lower cost when in comparison to big box store contracts since these institutions normally contract to outside thus increasing overall costs via financial cuts involved.
f) It's very highly recommended to perform an energy audit especially using firms who do just that, i.e. on other service thus avoiding skewed responses prior to the actual purchase.
g) Neighborhood HVAC specialists (approved and certified) are better since in some cases permits are involved and they can obtain/know how to.
If you are looking for opinions on the equipment I think you will get mixed feedback on both units. Opinions on equipment preferences is as variable as the people from whom you solicit those opinions. For example, I have alot of experience with the York product and very little with the Carrier product. Based on my knoweledge I would recommend the York system, as it is the highest efficiency furnace on the market. Carrier I'm sure has a fine product there, but I don't know enough about it to make a valid comment. One consideration for those two proposals you outlined would be the amount of heating you so versus the amount of cooling you do. The York system is inclined more to efficiency on heating with the highest AFUE and the Carrier is more inclined towards cooling efficiency with the higher SEER rating.
It's not rocket-science...
It's electromechanical thermodynamic engineering
"Have you had an energy audit done on your house yet? Did these contractors perform manual J calcs on your home?"
No calculations were done, contractors witnessed existing units and priced new replacement units of the same size. They interviewed me on if heat and A/C was okay on old system, therefore size requirements would be okay for new units. They walked around house looking at ductwork size, locations and set up.
Does anyone have specific experience with these exact units or can guide me with my decision.
Thanks in advance.
Why replace the system if you are just putting in the same old stuff, do you want increased efficiency and increased comfort or not? Calculations help the contractor decide if you need smaller equipment(which is very true in many cases) due to updated portions of the house, more trees around the house so less cooling is required and many more things. I have been to many houses where are 4 ton unit is installed for AC and they only need a 3 ton, yes the 4 Ton worked but not well and not efficiency.

Also don't miss the importance of sealing your ducts and possibly house. If you can save 20% of your airflow you can often size down your equipment by 20% saving energy and upfront costs by being able to use a smaller unit. You might want to try the contractor locator map on this website for a contractor that will do a better diagnostics for you.
